Abstract

L'invention concerne une carte mémoire supplémentée par un module de communication sans fil et un terminal pour utiliser une telle carte. Une mémoire externe est fournie à terminal de communication, et une carte mémoire présentant des informations correspondantes est prévue pour être utilisée avec ladite mémoire. Cette carte mémoire est reliée au terminal de communication qui ne comprend pas de module de communication sans fil, afin d'obtenir une fonction WPAN (réseau personnel sans fil) destinée au terminal de communication. Cette carte mémoire comprend le module de communication sans fil supplémentaire pour obtenir une fonction WPAN destinée à un terminal de communication, sans une telle fonction de communication sans fil. Puisque la carte mémoire est insérée dans la fente à carte du terminal de communication, le module de communication sans fil doté de la carte mémoire supplémentaire est protégé des impacts extérieurs. Comme l'utilisateur n'a pas besoin de séparer la carte mémoire de la fente à carte lorsque le module de communication sans fil n'est pas utilisé dans le module de communication, cela évite de perdre ledit module de communication sans fil
